ADJUSTABLE surronr FOR BEDS.

Application filed January 6,

J. CURTIS,

beds, as heregeneral type supporting Home or head "adapted to be locatedat one or both ends of tress in place thereon,

a bed and to beadjustable so its to occupy upwardly or downwardlyinclined positions The support is especially advantageous gfor use inconnection with ini nlid beds to vary the positions of portions of the'body of the occupant of the bed. I

The invention resides particularly in the special means employed forpivotally inounting the supporton the franieof the bath-for holding thesupport in adjusted positions, and in the peculiar operating mechanismfor the said holding means.

Inthe accompanying drawings: Figure- 1 is a plan View of o bed frame andmatthe mattress being broken away to bring out more clearly thearrangement and construction of one of the adjustable, supportsconstituting the invention. Fig. 2 is a fragmentary perspective View,certain parts broken out more clearly the portions of the lockingmechanism. Fig. 3 is a. fragmentary view showing the locking mechanismin elevation.

connection. with couches, lounges, or the like.

n ce the adjustable supports 4:, illustrated as located at opposite endsof the bed'in' Fig, 1, are of identically the same construction, oneonly of said supports will not he described;

Each support 4 consists primarily of a U-shaped frame made of tubing, orthe like, the sides of the support being provided at their free endswith downwardly projecting arms 5, and being pivotuliy connected esshown at 6, to the side rails l of the bed. The pivotal connectionshetwecn the sides of the support 4; and the bed are established by theprovision of plates 7 formed with suitnble hearings for the pivots (5above: referred to. The plates 7 C611): prise body upper end anoutstanding flange 8 which extends overthe adjacent rail 1 and isfastened thereto by a screw 9 or similar fos- Near its curved edge poris"formed with a. plurality otopenings 10 made by punching out portions ofthe metal of the plate at intervals, and a. sliding catch 11 formed witha curved engaging nose mounted in a transverse opening 12 formed in thelower end or the adjacent arm 5, and is adopted to engage with theopenings 10 of the plate 7 in order to cooperate in locking the support4: at a. predetermined adjustment.

The catches 11 supported on the arms 5 of the support l have springs 13'engaging the some and normally tending to project the catches intoengagement With thejplntes T. Extending inwardly from each arm 5 of thesupport 4 is a lug lion which is pivoted a hell crank lever 15, one armof which bifurcated and slott-edQas shown at 16, the other arm having2i. flexible connection 1? A pin.l8 ext-ending vertically through theinnermost end portion-of bifurcated portion 16 to thereby connect theparts and 11 together.

portions of npproxnnately semi circular shape and each plate has at itsThe connect-ions 1 17 lead from the pivoted ends of the sides of thesupport 4 to the end her 4 of said, sup;- port Where each connection isattached to the outer end of a lever 19 which is pivoted;

Movement of the levers 19 in the mat ner.

mentioned is adapted to'create a -pt1ll on the /connections 17, therebyimparting plvotal movement to the'levers l5 and withdrawing thecatches11 from their engagementwith the plates 7, under which conditions thesupadjustment.

'7, and the noses of the catches l1, 'aid port 4 is free to be'loweredto any suitable Owing to the peculiar manner of formation of theopenings 10 of the plates catches may have a sort of ratchet move entwhile engaged with the plates 7 so thatl the sppports Loan be readilyraised by merely gras iing the end bars thereof and withoutanymanipulation of the handle 21. During such upward movement of thesupports 4,

' ,the catches ratchet freely into and outof structure of the supportingmembers which carry the support a, this bein of advantage in a device ofthe class descri ed.. A

By reason of the peculiar mounting of the handle 21 upon the end bar ftof the supports, said handle is always in a convenient location to bemanipulated by the hand of the operator which grasps the support ineiiectingany adjustment of the lat- ,ter.

The flexibility of the connections 17 is .necessary in order to permitfree ratcheting movement of the catches 11 during upward movement of thesupport 4.

.The manner of connection of the support with. the plates 7 isespecially advantageous, as mentioned above. Pivots 6 are uti- .lizredfor this purpose and these pivlotsreally constitute extensions at the.upper ends of braces 6 thatare secured at their lower ends to the crossbar 23. The pivotextensionstt pass through openings or bearings in theend portions of the sides ofthe supporte'tand enter openings intheplates 7 to establish the desired pivotal connection be- ,tween theparts 4 and], as shown most .clearly in Fig. 5 of the drawings.

Tll9 cooperation of the handle 21 with the levers 19 is illustrated inFig. 6 where it will he noted that the handle 21 is rotatable and iscarried by a stem 21. passing through the I part 4.) of the support 4.On the lower, end

of the stem 21 are mounted spaced disks 2]. between which the free adacent ends of the levers warereceived, said ends being ;,e igageablebyan eccentric 21 located inter- ,n edialefifthe members 21".oscillatory sismovement'of'the' levers 19 may be effected crank leverspivoted to the'free end portions of said arms, horizontally operatingcatches supported on said arms and each connected with one arm of anadjacent bell crank rlever, and manipulative means connected with theother arms of the bell crank levers to control engagement of the catcheswith the plates whereby to hold the support at predeterminedadjustments, saidplates having suitable engaging portions to 006peratewith the catches.
